SPECIFICATION forming part of Letters Patent No. 736,213, dated August11, 1903.

Application filed Januaryl'l, 1903. Serial No. 139,454. (No model.)

To all whom it may concern:

Be it known that I, FRANK B. CASE,L citizen of the United States, and aresident of Rochester,in the county of Monroe and State of New York,have invented an Improved Connection for the Swinging Elements ofCameras, of which the following is a specification, reference being madeto the accompanying drawings, in which- Figure 1 is a side View of acamera in its opened position, showing the mechanism for adjusting thebed relatively to the back of such camera. Fig. 2 is a View from theright of the parts seen in Fig. 1, with the exception that thelens-standard 0, lens (hand bellows e are removed. Fig. 3 is an enlargedsectional view taken along the dotted line as y in Fig. 1 with all partsto the right of such line removed and shows only enough of that,

side of the camera-back a toward the observer in Fig. 1 to clearlyindicate the method of securing the pin j to such camera-back and theadjusting of the same, while Fig. 4: is a similar sectional view takenin the same way along the same plane and shows only enough of the otherside of the cameraback a away from the observer in Fig. 1 to indicatethe method of securing the pins j to such camera-back.

Fig. 5 is a top view of the camera and shows the handle h for adjustingthe pin Fig. 6 is a face view of the slides g g as secured on the insideof the camera-back a. Fig. 7 is an enlarged sectional view taken alongthe dotted line :0 g/ in Fig. 2, with all parts above such line removed,and shows enough of the left-hand side of the camera-back a as seen inFig. 2 to indicate the method of securing the slide 3 to suchcamera-back.

In folding cameras, as usually constructed with a swing-back, anyadjustment that has been effected between the back and the bed has to beentirely disarranged by the closing of the camera. objection to theswing-back camera as usually constructed-that is, those of the foldingtypeand another objection has been found in that-the adjustment is notusually lockedthat is, the camera-back and the camera-bed are not lockedin any position of adjustment, but they are moved to the desiredadjustment This has been one serious and then afterward locked byseparate screws or clamping devices especially for that purpose.

It is the purpose of my present invention to overcome these defects andprovide a swingback for a camera which shall make it possible to fold orclose the camera without disturbing the angular adjustment between thecamera-back and the camera-bed when they are again opened out intooperative position, and'one also in which the angular adjustment betweenthe camera bed and the cameraback is secured by means of a device whichpositively holds the parts in any desired position of adjustment withouthaving to resort to the cla1nping-screw or other device for holding theparts when adjusted as desired.

Referring to the drawings, a is the cameraback and b the camera-bed,hinged thereto at t in the usual way. The usual sliding brace f is seenarticulating at p with a bracket 7", secured to the bed 1;. A similarbrace f bracket 0", and pivot 19 are used on the side of the camerafarthest from the observer in Fig. 1 and as indicated in Fig. 2. Theupper ends of the braces ff normally articulate in the usual way andwhen desired may be made to slide by means of the usual slots thereinupon the studs j and j, respectively, secured to the slides s and 3,working in the guide-pieces g g, secured to the inside face of thecamera-box a. A nut at is secured upon the back face of the slide 5, andthrough this nut 11 there is arranged to work the threaded rod 3 in sucha way as to raise and lower this nut n and the slide .9, attachedthereto, when this screw-rod s is turned to the right or to the left bymeans of the handle h, secured to the top thereof. This screw-rod s isprevented from moving up or down by being shouldered through the platea, secured at the bottom of the conically-shaped recess in the top ofthe camera-back a and near the side thereof toward the observer, asindicated in Fig. 1. The brace f makes similar connection to thatalready indicated and described in regard to the brace f, with a stud jprojecting inwardly from the slide 5. This slide .9, however, has no nutthereon, but is held in frictional engagement with its guides oo 9 (onlyone of which is seen) by means of the spring located in a recesstherefor in the camera-back a and behind such slide 3. Any

one of the well-known devices for that purpose may be made use of fornormally hold ing the braces f and f in such positions relatively totheir corresponding studs j and j that such studs are normally held inthe upper ends of the slots in these braces f and f when once the camerahas been opened until, as usual in folding cameras, the braces f and fare pushed downward to the rear for the purpose of folding up thecamera. Such devices being well known in the art and forming no part ofmy present invention are not herein shown and no further reference isoperative range of the swing-back adjustment the camera may be closedand opened without disturbing the adjustment of the screw 8 by means ofthe handle 71, which serves not only to eifect the desired adjustment;but when itis effected this adjustment is permanently retained untilmodified by again turning the handle h.

What I claim is 1. In combination with a camera-back and a camera-bedhinged thereto, a brace articulating at one end with a bracket attachedto one of such camera elements, and at its other end with a studconnected to a nut working upon a suitable screw carried by the otherone of such camera elements, and a handle for operating such screw.

2. In combination with a camera-back and a camera-bed hinged thereto, abrace articulating at one end with a bracket attached to one of suchcamera elements, and at its other end with a stud connected to a nutworking upon a suitable screw carried by the other one of such cameraelements, and a handle for operating such screw accessible from the outside of the camera.

' 3. In combination with a camera-back and a camera-bed hinged thereto,a brace articulating at one end with a bracket attached to one of suchcamera elements, and at its other end with a stud connected to a nutworking upon a suitable screw carried by the other one of such cameraelements, a handle for operating such screw, and means for guiding andsupporting such nut.

4. In combination witha camera-back and a camera-bed hinged thereto, abrace articulating at one end with a bracket attached to one of suchcamera elements, and at its other end with a stud connected to a nutworking upon a suitable screw carried by the other one of such cameraelements, a handle for operating such screw accessible from the outsideof the camera, and means for guiding and supporting such nut.

5. In combination with a camera-back and a camera-bed hinged thereto, abrace articulating at one end with a bracket attached to one of suchcamera elements, and at its other end with a stud connected to a nutworking upon a suitable screw carried by the other one of such cameraelements, a handle for operating such screw, and a sliding connectionbetween one end of such brace and the member with which that end thereofarticulates.

6. In combination with a camera-back and a camera-bed hinged thereto, abrace articulating at one end with a bracket attached to one of suchcamera elements, and at its other with a stud connected to a nut workingupon a suitable screw carried by the other one of such camera elements,a handle for operating such screw accessible from the outside of thecamera, and a sliding connection between one end of such brace and themember with which that end thereof articulates.

7. In combination with a camera-back and a camera-bed hinged thereto, abrace articulating at one end with a bracket attached to one of suchcamera elements, and at its other end with a stud connected to a nutworking upon a suitable screw carried by the other one of such cameraelements, a handle for operating such screw, means for guiding andsupporting such nut, and a sliding connection between one end of suchbrace and the member with which that end thereof articulates.

8. In combination with a camera back and a camera-bed hinged thereto, abrace articulating at one end with a bracket attached to one of suchcamera elements, and at its other end with a stud connected to a nutworking upon a suitable screw carried by the other one of such cameraelements, a handle for operating such screw accessible from the outsideof the camera, means for guiding and supporting such nut, and a slidingconnection between one end of such brace and the member with which thatend thereof articulates.
